Abstract
The crystal and molecular structure of ammonium µ-nitrido-bis[aquotetrachlororuthenate(IV)], (NH4)3[Ru2NCl8–(H2O)2], has been determined from X-ray diffractometer data (MoK-α radiation, R= 0·071 for 1054 reflections). Unit cell dimensions are a= 15·910 A, b= 7·642 A, c= 8·399 A, γ= 121·09° with two molecules per unit cell, in space group B2/m. The compound contains ammonium cations and complex [Ru2NCl8(H2O)2]3– anions. The co-ordination about the two metal atoms in the anion is approximately octahedral. The two octahedra are joined by a bridging nitrogen atom, which is at a centre of symmetry. The Ru–N distances are very short, 1·725 A, indicating multiple bonding. The two independent Ru–Cl distances are 2·370 A and 2·391 A. The Ru–O(water) distance of 2·20 A is long by comparison with previously reported values.
